Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137436, here are decompositions:

23 + 137413 = 137436
37 + 137399 = 137436
43 + 137393 = 137436
53 + 137383 = 137436
67 + 137369 = 137436
73 + 137363 = 137436
83 + 137353 = 137436
97 + 137339 = 137436

Showing the first eight; more decompositions exist.
